Abstract

Calculateur numérique capable d'exécuter plusieurs opérations, comprenant un dispositif destiné à assurer une commande conditionnelle de ces opérations. Ce dispositif comporte des moyens de mémoire pour emmagasiner des mots d'instruction comportant une première et une seconde zones de commande correspondant auxdites opérations ; des moyens logiques de décision pour fournir un signal de décision d'après les résultats de décisions prédéterminées; et des moyens de commande conditionnelle qui réagissent aux première et seconde zones de commande et au signal de décision en sélectant la première ou la seconde zone de commande d'après le signal de décision, de manière à assurer la commande conditionnelle desdites opérations.Digital computer capable of performing several operations, comprising a device intended to ensure conditional control of these operations. This device comprises memory means for storing instruction words comprising a first and a second control areas corresponding to said operations; decision logic means for providing a decision signal based on the results of predetermined decisions; and conditional control means which respond to the first and second control areas and to the decision signal by selecting the first or the second control area according to the decision signal, so as to provide conditional control of said operations.
